请各位高手帮我看看这个例子,容器和金属接头用TIE连接,计算时出现下面的情况,tie pair出现问题,请各位帮我改一下,运算一下,谢谢!
For *tie pair (assembly_surf-rongqi-da-assembly_surf-jietou-da), adjustment was specified but no node was adjusted more than the adjustment distance = 2.22000e-16.
For *tie pair (assembly_surf-rongqi-xiao-assembly_surf-jietou-xiao), adjustment was specified but no node was adjusted more than the adjustment distance = 2.22000e-16.
187 elements are distorted. Either the interior angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.
The system matrix has 2 negative eigenvalues.

另外例子里因为不会给封头赋纤维材料,我用的是同性的代替,筒身上用的layup. 大家有没有做这方面的,请指点一下! |
